Chan, C.W., Cheng, K.K., Lam, L.W., Li, C.K., Chik, K.W., & Cheung, J.S. (2008). Psycho-educational intervention for chemotherapy-associated nausea and vomiting in paediatric oncology patients: A pilot study. Hong Kong Medical Journal, 14(5 Suppl.), 32–35.
To assess the feasibility of using relaxation and patient education
Patients were placed in group 1 or 2 (no randomization information provided). Group 1 received training in progressive muscle relaxation (PMR) and guided imagery (GI) using audiotapes daily. Training was provided daily on days 0-5, then patients practiced the techniques daily for two months. Group 2 received two 30-minute patient/parent education sessions on days 0 and 2, focusing on risk assessment, antiemetic use, and meal planning. All subjects completed instruments at baseline (prior to chemotherapy) then daily for seven more days. One and two months after the intervention, anxiety, compliance with PMR and GI (group 1 only), satisfaction with care, and quality of life was assessed. Pulse and blood pressure were reported in the findings but not listed in the procedure. A third group was comprised of 10 historical control cases who matched the characteristics of group 1.
The study was conducted at a single site hospital in Hong Kong.
All patients were pediatric and in active treatment.
This was a clinical trial with pre- and post-test design.
At baseline, group 1 had significantly lower anxiety than group 2 (p = 0.032). Group 1 had less vomiting on day 3 compared to the control group (p = 0.036). No significant difference was found in antiemetic use between the intervention and control groups. No significant difference was found in body weight, CINV, antiemetic use, quality of life, or caloric intake between groups 1 and 2. Health diaries indicated that patients practiced PMR three to four times weekly at home with no significant changes in blood pressure or pulse. Patients and parents reported the interventions as moderately useful.
This study was poorly designed, and findings should be used cautiously. Although the authors reported that PMR and education can reduce CINV, no conclusions should be made except that further research is warranted.
The quality of this study is too poor to provide any implications for nurses. Well-designed research in this area is needed.
